Figure 14: The result of one simulation run when using the simulation scenario that each node participates in the network with the probability randomly assigned in between 60% and 100% at every time and the environment dynamically changes. The time variations of search failure rates are drawn in the subfigures (a), (c), (e), and (g) and the time variations of the topology reconstruction ways are drawn in the subfigures (b), (d), (f), and (h). The time variation of the topology reconstruction ways is represented by a sequential line graph, in which drawing a line on the upper side stands for the use of the evolutionary reconstruction strategy and drawing a line on the lower side stands for the use of the random topology reconstruction.
